\ 2 Claims. (01. 92-4s) 1 This invention relates to improvements in paper-making'apparatus and is directed more particularly to improvements in novel slice apparatus for paper der type.

The principal objects of the invention are directed to a slice of novel form in combination with the vat and cylinder mold of a paper-mak-.

ing machine. The slice of the invention may be moved up and down relative to the cylinder mold and varied in width or made to assume various angular positions so as to obtain different various desired efiects.

making machines of thecylin- That is, the slice of the invention is so constructed and arranged that" as a unit it may be moved up and down relative to an adjacent wall of the vat and cylinder mold so. as to vary its position while at the same time its side walls or members are independently movable relative to one another and to the wall and cylinder mold to bring about various conditions.

.By means of the novel apparatus, it is possible to vary the space between the walls of the slice and the vat wall and the cylinder mold so as to obtain various desired effects in the .operation of, the paper machine. It is possible to control the action or flow of the paper making material onto the cylinder mold so as to obtain the said mold and thereby to obtain the desired intermingling of the fibers.

The novel features of the invention are adapted for broad application, but are hereinafter disill the desired depositing of paper making fibers on closed in connection with'the present preferred form of the invention. that variouschanges' and modifications may be made to adapt the slice mechanism of the invention to various paper making machines without departing from the spirit and scope of the invention.

In the drawing:

Fig. 1 is a transverse sectional elevational view through the vat of a paper making machine of the cylinder type and having the slice mechanism of the invention associated therewith;

Fig. 2 is a partial plan view of the vat shown in Fig. 1 and showing a portion of the slice mechanism associated therewith;

Fig. 3 is a partial sectional elevational view through the upper portion of the central member of the slice mechanism and showingthe actuating means for the side members of the slice; and

Fig. 4 is a partial sectional plan view through It will be understood the central member of theslice and guide means associated therewith.

Referring now to the drawing more in detail, the invention will be fully described. I

Side walls of thevat of a cylinder type paper making machine are represented by 2 and '4 and one end wall thereof is represented by 6. The opposite end wall is similar to the wall shown but' as it formsno part of the present invention it is not shown herein. 1

An inlet for the paper making material is represented by 8. A" wall IO' disposed on an incline and extending between end walls 6 is connected to the wall 2 by a lower wall I2. A curving wall i4 extends between wall I0 and a vertically disposed wall i6 which extends between the end walls 6. A bottom wall i8extends between the walls '4 and I6 and the outline ofa rotatable cylinder mold is represented by dot-dash lines In the operationof the apparatus paper making material flows through inlet'il into a chamber formed by walls '2,.-l 0 and'l2 and the end walls 6. In said chamber there may be baffles or other means-to provide the desired turbulence and action of the paper making material which ,slice mechanism is movable up and down and its walls 24-and 26 are independently movable. The slice as a whole may be positioned as desired relative to the wall "I and cylinder mold 20 while its walls 24 and 26 maybe disposed relative thereto independently of one another. In this waythe action or flow of the paper making material is controlled so that more or less thereof is caused to flow either upwardly or downwardly onto the mold.

That is, according to the general location of the slice and the angular position of the walls 24 and 26 relative to the wall l0 and the cylinder 20 more or less'of the paper making ma.- terial will be caused to take an upward or downward course as may be desired according to the particular type of paper being formed, charac- I ative to center wall teristics of the paper making material, speed of the mold and'other conditions.

End members 30 are provided, one adjacent each end wall 6, and a center supporting wall 32 extends between the end members; Said wall isguided in some suitable manner for up and down movements. In the form of the invention shown such guides as are provided for n guiding the plate 32 but it may be guided in various ways. V

Brackets 36 extend upwardly from each of the end wall members 6.. In-their upper ends nuts such as 38 are rotatable which are associated with hand wheels 40., Rods 42 in threaded en-;

gagement with the nuts 38 have their lower ends suitably secured to the center wall member-32. c

As the hand wheels '40 are rotated'in one direction or the other, the center wall 32 and 4 thereby the slice mechanism is raised and 'low-' ered toposition the slice as may be desired relative to the wall I and cylinder mold 20.-

Thelower ends ofthe outer and inner wall members and 26 of theslice are preferably hingedly connectedin some suitable way .to. the

' lower end of'the center wall 32zas'by hinges indicated by 44 so that said walls 24- and 1 may swing independently of oneanother tdwa'rds and away fromthe center plate 32. 1 1

Rods 48 and 4! have/their outerends/ pivoted to brackets so which are'flxed to the uppersides of thewall members 24 and 26", as shownri' Bearings or guides 5| slidablyf' receive the' rods' 46 and and these guides carry pivots 52 that are journalled in brackets associated with the up-v per sidefof the center plate I2. The parts described or some other suitable means permit the rods to assume various angular positions rel- 28 may swing,

a The upper ends of the rods 46 and4lare threaded, as shown. Internally threaded members 56v and 58 at each-side of-,eachbearing or guide 5| threadedly engagethe rods 46 and 48. by rotating the members 56 and" in one direction or the other,the'r ods 48 and 48 are moved through guides 51' to swing wall members 24 and 26 inand out so as t osition said walls The members I! and 58 not but serve as locking means to hold the said rods against movement. I v v If desired the lower ends of walls '24 and 26 may be more or less immovably fixedto the center plate 32 and be formed of such material that they may bend or flexso as torbe movable into various relative positions n order to obtain the desired adjustment;

:2 so that the walls24 and 'supportmember. 1 H usebetweenthe cyl- If*2,ao4,7as r I From the foregolns'it will beobserved that T the slice mechanism is movable up and down so that its general position maybe varied relative. to thewall l0 and cylinder mold 20 Also as 1 I will be noted the side plate members are independentlyZmovable so that they may bepositioned as may be'desired relative to their respective wall l0 and mold 20.

While I have describedv the invention in great detail andwith respect -to the present" preferred form thereof, itis'not desired to be limited there a to since changes and modifications maybe made 4 therein without'departing from thespirit and scope of lthe invention. The invention may be J embodied in other specific forms without departing from the essential characteristicsthereof;

' The present, embodiments are therefore to be 1 a considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended'claims rather. than by the foregoing description, and all changes which come within the meaning; and range of 'equiva-- lency of the, claims are therefore intended to b embracedtherein.
